Working in Inches

[bidgeeman]

Hi bogs.
Many thanks to you! It worked it out to .222 sets a pixel perfectly to a 1/16th of an inch.
There are two fields. One field is where you type in "Inches" and this field is processed by:

Code: Select all

   put fld "Inches"  /  0.222 into Hloc
multiply Hloc by 16

The second field is for 16ths and is processed by:

Code: Select all

   put fld "16ths"  /  0.222 into HlockB
   set the left of graphic "Box"  to Hlock + HlockB

This works perfectly but I need a way to limit the field for 1/16ths of an inch to "16".
Is there a way to do this that prevents the user typing in a value over 16?

Thanks again for all the great help on this forum.

I really don't know how you could do that as the user types for the simple
reason that the user will not type "16" s/he will type "1" and then "6".

I suppose you could have a routine to see if the user types 1 or 2 glyphs and then,
if they type 2, check what the second one is . . . .

That stack taught me two things thank you richmond62
The code was perfect but "ask" commend I had not come across yet.
I have often wondered how you could make a pop up screen that asks
"Do you want to continue? Yes or No".
How do you script in button for yes or no in the a"ask" function?



EDIT: Ahh...I found this:)

Code: Select all

answer "Go ahead?" with "Yes" or "No" or "Maybe"

But...I guess you need to put in an "if then" to proceed?
I'll have a play. This is so much fun!

Thank you again
Bidge

Hi richmond62
Is it possible to apply your curtailer code directly into a text field rather than a button?
I'm not sure what the command is if there is one?

Thanks

The only thing I can think of (but I just woke up, so take it with a grain of granite) would be something like

Code: Select all

if char 2 of field "yourFieldNameToCheck" > 6 then {rest of your code to show the message, blank the box, etc here}

You'd have that fire (ideally) either after they leave the field, or before they can type or click anywhere else , sorry, not awake enough to give a more coherent response

Dunno how "char 2" could be bigger than 16 . . .

How about this:

if (char 1 of fld "XXX" is "1") and (char 2 of fld "XXX" > 6) then
put "Too big, my friend" into fld "XXX"
end if

That is because you skipped over this part

The only thing I can think of (but I just woke up, so take it with a grain of granite)

You are correct, in your correction, just verify char 1 is < 2, and char 2 is < 7 I say char 1 less than 2 because it could easily be "0", as in "05".

Only glancing at this thread now and again, but am intrigued by the statements:

if char 2 of field "yourFieldNameToCheck" > 16...

...and char 2 is < 17

Maybe I am out of the loop, but...
